Support for per-domain authentication sources and methods

[rjl]

Ideally, in the common scenario in which each domain represents a downstream customer with his own authentication source, it would be nice to let that be configured as a domain-based property in Maia.

That is, domain1 might authenticate via POP3 at pop3.domain1.com, whereas domain2 might authenticate via LDAP at mail.domain2.net, and so on.

Richard Whittaker suggested a crude way to accomplish this, at least for authenticating against different servers of the same type. His solution involved reading/setting a cookie that indicates which server to authenticate against. Note that this code was submitted in 2004, and may not work as-is with modern versions of Maia.

In config.php:

if (!isset($_COOKIE['podomain'])) {
    setcookie ("podomain",$domain);
}
 
$podomain = $_COOKIE['podomain']; 
 
if (($podomain == whse) || (!$podomain)) { 
    $auth_imap_params = "{server1:143/imap/norsh/notls}INBOX";
} 
 
if ($podomain == ylkn) { 
    $auth_imap_params = "{server2:143/imap/norsh/notls}INBOX";
} 
 
....etc...

if (!$auth_imap_params) { 
    $auth_imap_params = "{server1:143/imap/norsh/notls}INBOX";
}

The same principle could be used to authenticate against multiple SQL, LDAP, or POP3 servers of course, as long as they're all servers of the same type.
